Researchers in Iceland have developed new technology that allows lower limb amputees to control their prosthetic legs with brain impulses. This means that the prosthetic can function in the same way as a real leg. Amputees are fitted with a sensor in their muscle tissue, which then transmits signals to the prosthetic leg, telling it what to do. Amputees can control the prosthetic with only their thoughts. This is a huge advancement in the world of medicine and it is going to be life changing to a lot of amputees out there.
